I have to refocus / re-collimate it anyway... I'm ripping a laser diode
out of a PlayStation3 laser sled and will probably be installing it in
an Aixiz heatsink. Should be a good bit of fun. Polymorph should be good
for making up the mounting bracket.
Fortunately when I was assembly the CX
scanner, I on;y had to make sure the beak was going in the right places...
Indeed. The laser assembly on the SX and CX seems to be a 'blob' sitting
on one side of the scanner, with a fixed focus lens tied in.
Getting down
to 0.08mm is going to be interesting, what with
beam-scatter and fluorescence. And I really don't like the idea of using
a focus-finder to set it up... viewing a laser through a magnifying lens
seems like a really dumb idea to me, even with safety goggles.
'Do not look up this laser beam with your remaining eye' :-)
Actually it's:
WARNING
BIG SCARY LASER
DO NOT LOOK INTO BEAM
WITH REMAINING EYE
:)
When I have a chance I;ll dig out what schematics I
have of the CX and SX
enginers and get copies to you...
No hurry. I've got a weekend of finishing assignment work ahead of me...
need to finish off my B.Sc project report, and one of my module
assignments. Fun!
